I command the listbox to an item in the listbox and it gets highlighted. The listbox is only high enough to show 15 of the 100. The item highlighted is at the bottom of the list out of view. Is there a way to bring into view (scroll up/down) the item that is highlighted in the listbox when it is commanded without having to manually scroll up or down to see it ? _________________ iMac 27" (2.8GHz Intel Core i5, 16GB RAM, 1TB Drive) OS X Lion 10.7.3 and Windows 7 Toshiba Laptop Running Windows 7 & WinXP SP3 REAL Studio Enterprise Edition 2012r1 http://www.theultimatecampgroundlog.com Being rewritten for the Mac Top HMARROQUINC Post subject: Re: Listbox scroll questionPosted: Sun Jan 27, 2013 6:15 pm Joined: Sun Jan 25, 2009 5:11 pm Posts: 376 Location: Guatemala, Central America Something like this: dim i as integer for i = 1 to 100 listbox1.AddRow("Row: " + str(i)) next i listbox1.selected( listbox1.ListCount -1) = true listbox1.ScrollPosition = listbox1.ListCount -1 _________________ Future RS guru.

For example, you might do something like: Listbox1.ListIndex = X if X < 8 then Listbox1.ScrollPosition = 0 // top of list elseif X > Listbox1.ListCount - 8 then Listbox1.ScrollPosition = Listbox1.ListCount - 15 // end of list else Listbox1.ScrollPosition = X - 7 // center the row in the list display end Top ktekinay Post subject: Re: Listbox scroll questionPosted: Sun Jan 27, 2013 6:20 pm Joined: Mon Feb 05, 2007 5:21 pm Posts: 411 Location: New York, NY Use ScrollPosition, and I recommend that you use the selected item minus 1. For example: lb.Selected( row ) = true lb.ScrollPosition = row - 1 This will bring it into view, but not make it the topmost item. You can even get fancy with RowFromXY to see if the row is already visible before forcing a scroll. _________________ Kem Tekinay MacTechnologies Consulting http://www.mactechnologies.com/ Need to develop, test, and refine regular expressions?
